很抱歉我的解释让你感到困惑，但我认为你没有按键盘上的Ctrl键，我猜测你的鼠标上的后退键的处理方式与按Ctrl+Z相同，因为视频显示问题发生时，撤销按钮被高亮显示。然后我怀疑，如果修改键由于鼠标故障而被按住，它可能会有这样的表现。
无论如何，我想重现这个问题，但不幸的是，我没有带后退键的鼠标，所以我想看看Spine团队中是否有人能重现这个问题。
如果你找到了除使用鼠标上的后退键之外的方法来重现这个问题，请让我们知道。
Sorry that my explanation confused you, but I didn't think you were pressing the Ctrl key on your keyboard, and I guessed that the back button on your mouse treated it the same as pressing the Ctrl+Z, because the video shows the undo button was highlighted when the problem was occurred. Then I suspected that if the modifier key was held down due to a mouse malfunction, it might behave that way.
Anyway, I would like to reproduce the problem but unfortunately I don’t have a mouse that has a back button, so I'll see if anyone in the Spine team can reproduce it.
If you find a way to reproduce the problem other than using the back button on your mouse, please let us know.
